Antigenic and biochemical characteristics of Mobiluncus mulieris and Mobiluncus curtisii

Tidskriftsartikel (refereegranskat)abstract
- Twenty-four strains of Mobiluncus mulieris and 27 strains of Mobiluncus curtisii were tested with respect to 6 different biochemical characteristics: arginin-decarboxylase activity, beta-galactosidase activity, synergistic hemolysis with Staphylococcus aureus, hydrolysis of hippurate, migration through soft agar and reduction of nitrate. Antigens of the same strains, prepared by ultrasonication, were subjected to sodium dodecyl sulphate-polyacrylamide gel electrophoresis followed by immunoblotting using polyclonal rabbit antisera against two of the M. mulieris strains and five of the M. curtisii strains. Two different strongly reacting protein antigens could be detected in the M. mulieris strains. These strains could be separated into three groups based on the possession of either of the two antigens or both. In the M. curtisii strains, 10 strongly reacting protein antigens could be detected. Four strains possessed only one of these antigens, one did not possess any, while the remaining strains possessed different sets of 9 of them. Within each species common protein antigens were detected. No antigens were found which were shared by both species. The biochemical characteristics studied could not differentiate between the antigenic groups in any of the species. None of the antigenic subgroups of M. curtisii found in the present study was identical with any of the two subspecies (curtisii and holmesii) which have been proposed.

Light and electron microscopic studies of anaerobic curved bacteria isolated from the vagina
- 1984
-
Ingår i: Scandinavian Journal of Urology. - 0300-8886. ; 86, s. 59-64
-
Tidskriftsartikel (refereegranskat)abstract
- Twenty strains of anaerobic curved rods isolated from vaginal secretion were studied with light and transmission electron microscopy. Ten of the strains were of a short (approx. 1.5 microns) Gram-variable type, while ten were of a long (approx. 3 microns) Gram-negative type. The former had one to four flagella and the latter between one and eight. The flagella originated from the concave aspect of the cells. Thin sections of both types of bacteria revealed an approximately 30 nm thick cell wall with no outer membrane, similar to that of most Gram-positive bacteria. An electron-dense zone in the middle of the cell wall, atypical of Gram-positive bacteria, was found, however. Amorphous and electron-translucent cytoplasmic inclusions, not membrane-enclosed, were detected. These inclusions stained metachromatically with Albert's stain.

Vaginal lactobacilli inhibiting growth of Gardnerella vaginalis, Mobiluncus and other bacterial species cultured from vaginal content of women with bacterial vaginosis

Tidskriftsartikel (refereegranskat)abstract
- On a solid agar medium the growth-inhibitory effect of 9 Lactobacillus strains cultured from vaginal content was tested on bacteria cultured from vaginal content of women with bacterial vaginosis: Mobiluncus, Gardnerella vaginalis, Bacteroides and anaerobic cocci. Inhibition zones were observed in the growth of all of the strains isolated from women with bacterial vaginosis around all lactobacilli. The inhibitory effect of the lactobacilli was further tested on various anaerobic and facultatively anaerobic species, both type strains and fresh extragenitally cultured strains. Four Bacteroides fragilis strains as well as 2 out of 4 Staphylococcus aureus strains were clearly inhibited by the lactobacilli. The inhibition zones were generally wider at pH 5.5 than at 6.0. For all inhibited strains, (the S. aureus excepted) a low pH on the agar around the lactobacilli correlated to wider growth-inhibition zones.

Determination of cotinine in urine using glass capillary gas chromatography and selective detection, with special reference to the biological monitoring of passive smoking
- 1988
-
Ingår i: Journal of Chromatography A. - 0021-9673. ; 454, s. 293-301
-
Tidskriftsartikel (refereegranskat)abstract
- A capillary gas chromatographic (GC) method using selected-ion monitoring (SIM) was developed for the analysis of cotinine (C.A.S. No. 486-56-6) in human urine. The method is based on basic extraction of cotinine from 2 ml of urine into dichloromethane. After evaporation of the dichloromethane solution to dryness, 100 microliters of toluene were added, prior to GC-mass spectrometric (MS) analysis. Trideuterated cotinine (C.A.S. No. 97664-65-8) was used as the internal standard. More than 1000 automatic chromatographic analyses were made without column degradation. Molecular ions (M) of cotinine and trideuterated cotinine, (m/e = 176 and 179), were monitored in the electron impact (EI) mode and m/e = 177 (M + 1) and m/e = 180 (M + 1) in the chemical ionization (CI) mode with isobutane. The correlation coefficient with SIM and EI was 0.998 (5-20 ng/ml) and with CI was (0.2-2 ng/ml). For thermionic specific detection the correlation coefficient was 0.998 (10-510 ng/ml). Only capillary columns with an apolar bonded stationary phase film thickness of 1 micron showed sufficient inertness for cotinine analysis at the sub ng/ml level. The relative standard deviations for 5 and 20 ng/ml were 5.2 and 3.5% respectively (n = 12) using EI. Spiked urine samples from six non-smokers (5 ng/ml) showed a relative standard deviation of 5%. The overall recovery (25 ng/ml) was 100 +/- 4%. The minimum detectable concentration, using SIM, was ca. 2 ng/ml in the EI mode and ca. 0.2 ng/ml in the CI mode. The half-time for cotinine was ca. 18 h for both active smokers and non-smokers.

- In this comment we show that a recently proposed public key cryptosystem is not safe for most of the practical cases. Furthermore, it is shown that the security of this system is closely connected with the problem of computing logarithms over a finite field.

GENERAL CLASS OF WINDMILL POLYNOMIALS FOR FAST M-SEQUENCE GENERATION.
- 1986
-
Ingår i: ; , s. 115-115
-
Konferensbidrag (refereegranskat)abstract
- Summary form only given. The windmill technique is an attractive alternative to the Lempel-Eastman technique for fast m-sequence generation. The author has generalized the class of linear recurrence relations for which the windmill technique results in an m-sequence generator. A converse to a set of known necessary conditions has been obtained.
